If you're in Nairobi you must see this wildlife park. Roaming across the park are lions, zebra, giraffes, white rhino, black rhino, hippos, buffalo and lots of native birds. You need a 4x4 and a map or hire a local guide. Entry fee is a little high - but remember tourism is a key source of revenue for Kenya. If you missed anything while you were driving around in the 'wild', then there's an orphanage just next to the entrance/exit.
